About 400 soldiers on the ground in Pierrefonds had their hands full on Thursday.
They spent hours reinforcing a dike near the water treatment plant.
After that was completed, more time was put towards pumping out water from nearby streets.
Less than a week ago, three dikes broke in Pierrefonds causing flooding.
Most residences in the area have been evacuated, but some people have returned to their homes to comb through the damage.
For residents of Dauville Street, seeing soldiers in their community was a welcome sight.
“For us, they came in and all this big stuff – they helped me move it out,” said Roy Pretty, a Pierrefonds resident. “It was a good help for me because I couldn’t do it by myself.”
Leblanc said Thursday’s goal was to seal the area protected by the dike and then pump out water into the nearby Rivière des Prairies.
